SVCL Inrush Current Limiter

The SVCL2800S Series of space qualified Inrush Current Limiters are operable over the full military (-55 °C to +125 °C) temperature range with no power derating. The SVCL2800S is designed to control the inrush current drawn by VPT’s EMI filters and DC-DC converters during turn-on. The SVCL2800S functions by limiting the rate of rise of its output voltage, and will also control the inrush current of discrete input capacitors.

The SVCL2800S Series of Inrush Current Limiters is radiation hardened and suited for use in low Earth orbit (LEO), medium Earth orbit (MEO), geostationary orbit (GEO), deep space, and launch vehicle programs.
